Blood flow in arteries can exhibit jerks or pulsations primarily due to the rhythmic contraction of the heart, which creates pressure waves as blood is pumped into the arteries. This pulsatile flow is influenced by the elasticity of the arterial walls, which expand and recoil with each heartbeat. Additionally, factors such as blood pressure and the overall health of the cardiovascular system can affect the smoothness of blood flow, leading to more pronounced jerks or fluctuations.
What else can I help you with?
Why do blood flows in arteries in jerks?
Blood in arteries moves because of pressure of blood from the heart. Each time the heart pumps, it pushes the blood a little further. Veins do not rely on the heart to move blood. Veins have a system of valves to keep the blood from not moving backwards, and muscles contract the veins to move the blood.

Do arteries flow to the heart or away from the heart?
Arteries flow away from the heart. That's a technical answer. Some blood tubes that look like arteries flow into the heat to nourish it. Of interest is the pulmonary artery, the only artery to carry un-oxygenated blood. It carries blood to the lungs where it is oxygenated.
